在内蒙古自治区阴山北部农牧交错带耕地表土33组颗粒分析实验数据基础上,运用M atlab软件对VanGenuchten等模型进行模拟求参,并得到能较为精确地表征当地土壤颗分曲线的数学模型,以期为全面综合分析阴山北部农牧交错带风蚀沙化地表土壤的抗风蚀能力有所帮助。
Based on the experimental data of 33 groups of cultivated topsoil in the ecotone between agriculture and animal husbandry in the north of Inner Yinshan Autonomous Region, Matlab software was used to simulate the model of VanGenuchten, and the mathematical model was established to characterize the soil particle fraction more accurately. It is helpful to comprehensively analyze wind erosion resistance of wind erosion and desertification soil in the ecotone between agriculture and animal husbandry in North of Yinshan.
